Screw pump It is widely used in sewage treatment plants to transport water, wet sludge and flocculant liquid due to its characteristics of variable transport, strong self absorption capacity, reversible, and the ability to transport liquid containing solid particles. IMO screw pump The selection shall follow the principles of economy, rationality and reliability. If the design and type selection are not well considered, it will bring trouble to the future application, handling and repair. Therefore, selecting a reasonable and reliable screw pump according to the actual production needs can not only ensure the smooth production, but also reduce the repair cost. Now let's introduce our understanding of using screw pump. Screw pump sewage treatment screw pump is widely used in sewage treatment plants to transport water, wet sludge and flocculant liquid because of its variable transport, strong self-priming capacity, reversible, and the ability to transport liquid containing solid particles.

The selection of screw pump shall follow the principle of economy, rationality and reliability. If the design and type selection are not well considered, it will bring trouble to the future application, handling and repair. Therefore, selecting a reasonable and reliable screw pump according to the actual production needs can not only ensure the smooth production, but also reduce the repair cost. Now we will introduce some insights we have gained in the use of screw pump as follows: the flow of screw pump is linear to the speed of screw pump. Compared with the screw pump with low speed, the high speed screw pump can increase the flow and head, but its power increases significantly. The high speed speeds up the wear between the rotor and stator, which will inevitably lead to premature failure of the screw pump, Moreover, the length of the stator and rotor of the high speed screw pump is very short, and * * * is easy to wear, so the service life of the screw pump is shortened.

The speed of the screw pump is reduced by the speed reducer or stepless speed regulator to keep the speed below 300 revolutions per minute. Compared with the high-speed screw pump, the service life can be extended several times. The quality of screw pumps There are many kinds of screw pumps on the market now. Relatively speaking, the imported screw pumps have reasonable design and excellent materials, but their prices are high. Some services are not in place. The price of accessories is high, and the order cycle is long, which may affect the normal operation of the production. Most of the domestic products are imitated from imported products, and the quality of the products is mixed. When selecting the domestic products, the products with low speed, long lead, good transmission components and long extra life are selected in consideration of their cost performance.
